Windows NT 3.1 build 511 is the original RTM build of Windows NT 3.1, which was released on 27 July 1993.

Changes from build 475[edit | edit source]

During the file copy stage in the graphical part of setup, the dialog with the progress bar has been moved to the lower-right corner. In the upper-left corner, there are now billboards showing the features and advantages of Windows NT as well as a reminder to register at Microsoft.

OS Loader[edit | edit source]

  • The message during boot to press the Spacebar to initialize the Last Known Good Configuration/Hardware Profile menu has been altered.
  • The menu entry to load a previous installed system from the C drive has been removed, letting Windows NT directly boot.
  • Changed the message of the boot screen (WINDOWS_NT_BANNER or 0x4000007E) to "Microsoft (R) Windows NT (TM) Version 3.1", now only reporting the system memory without the build number.

Bugs[edit | edit source]

Processor check[edit | edit source]

Setup doesn't detect processors newer than the original Pentium, as well as some models of 386, 486, and Pentium processors. To bypass this, two INF files must be edited after the first stage (in text mode) of setup is done. Change the line STF_PROCESSOR = "" ? $(!LIBHANDLE) GetProcessor to STF_PROCESSOR = $(ProcessorID_I586) in INITIAL.INF and SETUP.INF files in the SYSTEM32 subdirectory of the target installation directory. If you're doing this on a 386 processor use I386, and for 486 processor use I486 instead of I586.
